Abstract
A deep olefin internal olefin is reacted with a C.sub.3-4 primary alkyl aluminum chloride in the liquid phase in the presence of a catalyst system formed from (i) a dicyclopentadienyl dihalide or halohydride of zirconium or hafnium and (ii) a hydridic co-catalyst component. Unlike prior art procedures, negligible quantities of by-product paraffins are formed in the process.
